Marines - What Chapter - from Painting P.O.V.

I have a few models left over from my Salamanders (no, they are not done yet, but I am working on them, honest!) and thought I should use them (as I hate to sell them, since I won't get back what I paid for them, and other projects are still infantile in their planning).

I always thought crimson fists looked awesome, and were the centre of attention in the first 40K rulebook, rogue trader. Ultras are pretty cool but I dont like their Primarch, so that also rules out the sons of Guilliman and I think blue marines look better than yellow.
